PICKLING APFARATUS.

Specification of Letters Patent.

Fatented Mar. 12, 1218.

To all whom it may concern:

Be it known that I, DAVID KENDALL, a citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented a new and useful Improvement in- Pickling Apparatus, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a sectional elevation of a pickling apparatus embodying my inven- Fig. 2 is a plan view partly broken away of the pickling machine proper.

Fig. 3 is a section on the line III-III of Fig. 2; and

Fig. 4 is a detail sectional view of a portion of one of the chain sheaves with the chain in position thereon.

.My invention has relation to pickling apparatus, and more particularly to apparatus of this character for use in pickling pipe, rods, etc.

The object of my invention is to provide simple and convenient apparatus of this character by means of which pipe and the like can be readily and economically handled in quantities and efficiently subjected to the action of a pickling bath.

A further object of the invention is to provide apparatus of this character in which the pickling machine operates as a bail for handling the pipe, etc.

A still further object of the invention is to provide means of effective character for tumbling the pipes, etc., so that they will be thoroughly subjected to the pickling action throughout their entire surfaces.

The nature of my invention'will be best understood by reference to the accompanying drawings in which I have shown the preferred embodiment thereof, and which will now be described, it being premised, however, that various changes can be made in the details of construction, arrangement and combination of the various parts, without departing from the spirit and scope of my invention as defined in the appended claims.

In these drawings, the'numeral 2 designates a crane bridge mounted for longitudinal travel on the girders 3. 4 is a crane trolley mounted for transverse travel on the bridge 2. 5 is a hook block which is suspended from this trolley and which is provided with a hook 6 adapted toengage and suspend the pickling machine proper.

This machine comprises a suitable frame 7 upon which is mounted an electric motor 8. The armature pinion 9 of this motor drives a gear wheel 10 on the longitudinal shaft 11 which is connected by the gears 12 wlth a short shaft 13 carrying the pinion 14, which meshes with the gear 15 on one end of the second longitudinal shaft 16. The shaft 16 carries at each end portion a pinion 17 whlch meshes with the large gear wheels 18. The two gear wheels are mounted on opposite end portions of a lower longitudinal shaft 19 (see Fig. 3). To opposite end portions of this shaft are rigidly secured grooved sheave wheels 20, from which are suspended the carrying and tumbling chains 21, these chains being looped around the sheave wheels and hung therefrom. The chains are preferably of bronze or other metal which will not be attacked by the pickle; and in order to give the pipe an effective tumbling or rolling movement while they are in the pickle bath, the sheave wheels are made eccentric with respect to the shaft 19 and the two sheave wheels have their points of greatest eccentricity differently located.

22 designates a stationary platform which is supported above the series of pickling vats 23. This platform is provided over the vats with the locking lugs or projections 24 adapted to hold the pickling machine in proper position over the respective vats. For this purpose the machine is provided with the slotted lugs 25 adapted to engage the lugs 24, the engaging surfaces of these lugs being wedge shaped vertically.

In operation a quantity of the ipipe or other objects to be pickled are placed in the loops of the chains 21 as shown in Fig. 3. The pickling machine is then carried by the crane mechanism to a position over the pickling vats and is lowered on to the stationary platform 22 over the desired vat. The crane is then detached from the pickler and the motor 8 is started. The resultant movement of the chains 21, under the action of the eccentric sheave wheels, gives the pipe a constantly rolling motion on the chains. The different positioning of the two eccentric sheave wheels also imparts an up and down tilting movement of the pipe.

llhese combined movements are very efiective in bringing all portions of the surfaces of the pipe, both interior and exterior, in contact with the pickling bath, and in breaking up the scale.

The advantages of my invention will be readily appreciated by those familiar with this art, since it provides pickling apparatus by means of which pipe and the like in quantities can be conveniently handled, carried to, lowered .into, and removed from the pickle bath. Also apparatus of this character in which the objects to be pickled are, by the peculiar movements of the chains, thoroughly agitated or tumbled while in the bath, thus enabling the latter to exert its maximum effect thereon.

1. Pickling apparatus, comprising a portable carrier, means whereby said carrier may be moved into and out of operative relation to a pickling vat or tank, looped supporting and tumbling chains suspended from the carrier, and a motive device mounted on the carrier and operatively connected. to said chains, said motive device being independent of-the means for moving the carrier; substantially as described.

2. Pickling apparatus, comprising a carrier, looped supporting and tumbling chains suspended from the carrier, and means for actuating said chains to impart a rolling movement to pipes or other objects supported in the loops of the chains, and also for alternately raising and lowering the chains to thereby tilt the pipes back and forth in a longitudinal plane; substantially as described.

3. Pickling apparatus, comprising a portable frame, a shaft journaled on said frame, looped supporting and agitating chains suspended from said shaft, and means for rotating the shaft to move the chains longitudinally While holding the shaft in a substanta v 1,25%),02-2- tially fixed position with respect to vertical movement; substantially as described.

4:. Pickling apparatus comprising a portable carrier, rotary eccentric members mounted on said carrier, and looped chains hung from said eccentric members and arranged to support the articles to be pickled in the loops thereof, together with means for rotating the eccentric members to there by impart movement to the chains; substantially as described.

5. Pickling apparatus comprising a port-- able carrier, a plurality of eccentric members mounted on said carrier, said members having their points of greatest eccentricity difierently positioned, means for rotating said members, and looped chains hung from said members and arranged to support the objects to be pickled in the loops thereof; substantially as described.

6. The combination with a pickling vat,

of a support adjacent to and above the vat,

crane mechanism movable over said support, a portable frame adapted to be connected to and disconnected from the crane mechanism and to ,be moved to and from said support thereby, endless looped chains suspended from said frame and adapted to depend into the vat and to support the object to be pickled in the loops thereof, and motive means on said frame for actuating said chains; substantially as described.

7. Pickling apparatus, comprising a plurality of looped flexible supports for the objects to be pickled, and means for moving said supports to impart a combined rolling and tilting movement to the object supported thereby; substantially as described.

In testimony whereof, I have hereunto set my hand.
